DOGR-FASTENER.

Specification of Letters Patent.

Application filed December 1, 1913; Serial'No. 803,908.

To all whom it may concern Be it known that I, F RHDERICK SCHMID- ;.\i,1.. a citizen of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Imprmements in Door-l asteners; and I do declare the following to he a clear, full, and exact description of the invent-ion, attention being called to the drawing which accompanies this application and forms a part thereof.

This invention relates to door fasteners of the kind where the device in addition to its primary function for holding a door in closed position, serves also for the purpos of forcing thedoor tightly to its seat and likewise assists in disengaging it therefrom. Conditions for such use exist where fasteners of this kind are used in connection with doors having beveled edges which seat against jambs of complementary shape, as in the case, for instance, of doors for refrigerators, cooling rooms, etc. I

The invention consists of theparticular construction hereinafter described and claimed and as illustrated in the accompanying drawing, in which:

Figure 1. shows a front-view of the device connected in place and in door-closing position. Fig. 2. is a side view of the fastener, the door to which it is connected appearing edgewise, dotted lines showing how the fastener appears when in door-opening position. Fig. 3. shows the device in a horizontal section taken on line 33 of Fig. 1, and in door-closing position. Fig. 4:. in a similar view shows the device .in door-opening position. Fig. 5. in a vertical section of the device shows a modified construction of the same.

In the drawing, reference character 10, indicates a door which has a beveled edge at which it is fitted to a complementary jamb 11.

A, is a stop provided adjacent the jamh and B, is a match adapted to co-act there with. This catch is pivotally mounted between two vertically spaced flanges 12' and 13, by means of a pin 14:. These flanges project from a base plate 15, secured to the front of the door. Catch B is actuated by means of a lever 16 mounted at 17 and terminating in a handle 18. Said catch is provided with two fingers 19 and 21, either one of which is adapted to co-act with stop A, finger 19 to assist in unseating the door and finger 21 to force the same home to its seat.

As will be observed, lever 16 operates in a plane at right angles to the plane in which the catch moves and if moved outwardly as shown in dotted line in Fig. 2, it will act against a projection 22, on 'the catch,-as shown in Fig. 4, thereby causing finger 19 to bear against stop action is the unseating of the door, as shown in Fig. 4.. Catch B. remains in this position which leaves it in ready condition for closing and resenting the door. in this case, the door moving toward the jamb. finger 19 will strike stop A first, causing the catch to swing on its pivot H so that finger 21 will engage stop A on its other side. as shown in Fig. 3. If the lever is moved toward the door, it will bear against heel of the catch, which action will be transmitted to finger 21 and cause the same to bear against stop A as shown in Fig. 3. In its further effect this action causes the door to be firmly forced to its seat.

It. is-essential that catch B remains in the position shown in Fig. 4 and while the door is open so that finger 19, when the door is being closed may strike stop A, to actuate the catch in the proper manner as intended. For such purpose the catch is provided 'with a shoulder 24 adapted to seat against a stop 25 on the base plate. A spring 26 is provided in, the catch and. acts in a manner to force it toward said stop. It acts against the pivot pin 14: by-means of a follower 27. The opening in the catch through which the pivot pin passes is elongated to permit the catch to adjust itself for this movement. This elongation permits also the catch to disengage itself from stop 25 when finger 19 strikes stop A on the closing movement of the door as above related. Lever 16 moves within a. notch 28, formed in flanges 12 and 13 and whereby it is sustained in position. Stop A, is connected to a screw-shank 29 adjustably seated in a socket 31. In this manner'adjustment may be had to meet properly the position of the catch and to make up for changes due to warping, swelling of the wood, settling of the door, etc. The adjusted position of stop A, is secured by means of a set-screw 30 Which locks shank 29. It is desirable, especially where this device is used on larger doors, as for instance such as are found in cooling rooms, that provision is made to permit manipulation of the fas- Patented Mar. 31, 1914.

The cflect of this tener also from the inside. This is shown in Fig. 5, where a lever 35, similar to lever 16 is used on the inner side of the door and connected to said lever 16 by means of a link 36 which passes through an opening 37. This added lever is mounted upon a base plate 38 which may be similar to base plate a catch, a door, means whereby the catch is pivotally mounted upon said door so as to move in the planeof direction in which the door swings, a stop adapted to co-act with this catch positioned in a stationary position adjacent the free edge of the door and a manipulating lever pivoted to swing in a plane at right angles to the plane in which the catch moves and adapted to actuate the same for the purpose of engaging or disengaging the stop.

2. In a door fastener, the combination of a stop positioned stationary, a catch pivotally mounted upon the door and provided with two spaced fingers at one of its ends and with a projection spaced from its other end or heel, a manipulating lever mounted so as to swing in a plane at right angles to the plane in which the catch moves and positioned to occupy the space between said heel and projection and operating in a manner that when moved in one direction it engages the heel of the catch to cause one of the fingers of this latter to co-act with the stop to seat the door and when moved i in the other direction-it engages the projec tion mentioned to cause the other finger of purpose of unseating-the door.

3. In adoor fastener, the combination of a base plate adapted to-be mounted upon a door close to the free edge thereof and provided with two, vertically spaced, outwardly projecting flanges which have a notch between their ends, a catch pivotally mounted the catch and an operating lever pivoted on the base plate above the flanges mentioned and adapted to move within the notch therein and to engage the catch to manipulate the same with reference .to the stop.

4. In a door fastener, the combination of a stop positioned stationary, a base plate, a catch adjustably'mounted thereon and pr0- vided with two spaced fingers, an operating lever mounted so that when moved in one direction it is adapted to actuate the catch to cause one of the fingers thereof to co-act with the stop mentioned to unseat the door and means to hold the catch in this position while the door is open; said means comprising a' shoulder on the catch, a stop on the base plate and a spring adapted to move the catch so that the shoulder thereon enters into yielding engagement with the shoulder on the base plate.

5. In door fastening means, the combina tion of two levers pivotally supported so as to move in a vertical plane, one being pivoted to one side of the door and the other to the other side thereof, a link extending through a perforation in the door and free to move in an axial direction whereby these levers are connected to each other-between their ends so that manipulation of one lever actuates the other lever, a catch supported on one side of the door and in operative engagement with one of the levers and a stop positioned stationary and adapted to co-act with the catch. a

In testimony whereof, I hereunto afiix my signature in the presence of two witnesses. the .catch to co-act with the stop for the FREDERICK SCHMIDGALL.
